“…The potential voids are large enough to be filled via mutual interpenetration of four independent 3D frameworks, generating a fourfold-interpenetrating 3D structure (Figure f). To our knowledge, this 3D supramolecular network represents the first example of a Zn(II) MOF with the 3,4,4T25 topology sustained by the interplay of the coordinative and hydrogen-bonding interactions. , …”

Using reticular chemistry allowed the design and construction of four novel Zn(II)/Cd(II) coordination polymers, {[Zn(BTPA)(TPA)]•H 2 O} n (1), {[Zn(TTPA)(TPA)]•H 2 O} n (2), {[Cd 2 (TTPA) 2 (TPA) 2 (DMF)]•2H 2 O} n (3), and {[Cd(TTPBDA)-(TPA)] 0.5 •DMF•H 2 O} n (4). They were successfully synthesized from bi-, tri-, and tetratopic phenylamine derivatives (BTPA = bis(4-(1H-1,2,4-triazol-1-yl)phenyl)amine, TTPA = tris(4-incorporating a linear terephthalic acid (H 2 TPA) ligand and Zn(II)/Cd(II) nitrate salts. These transparent crystals present gradually increasing dimensionality and complexity upon extension of the denticity of the phenylamine organic building blocks, as clearly supported by single-crystal X-ray analysis, infrared spectroscopy, elemental analysis, powder X-ray diffraction, and thermogravimetric analysis. Complex 1 shows two-dimensional (2D) threefold-interpenetrating layers (2D + 2D → 2D) with the sql topology that are further formed into a three-dimensional (3D) supramolecular structure by interlayer π•••π stacking and hydrogen-bonding interactions. Complex 2 displays 2D layers with the hcb topology that are further assembled into a 3D fourfold-interpenetrating supramolecular framework with the 3,4,4T25 topology by hydrogen-bonding interactions. Complex 3 possesses a fourfold-interpenetrating 3D (3,4,5)-connected architecture with the 3,4,5T86 topology. Complex 4 features an interesting and unusual new self-penetrating (4,6)-connected 3D topological network with the point symbol of (4 14 • 8)(6 6 ), which contains a fourfold-interpenetrated 3D dia network linked by TPA 2− ligands. The results suggest that these diverse coordination networks mainly can be adjusted by the number of 1,2,4-triazole substituents on the aniline backbones and the coordination geometries of the metal ions. Furthermore, the photoluminescence spectra and emission decay lifetimes of complexes 1−4 were examined.

“…Advanced oxidation technologies such as the Fenton-like method utilize oxidation processes, which generate sulphate radicals that are very effective in degrading organic pollutants because of their strong oxidant power [32,33]. In order to investigate the catalytic activity of the complex, degradation experiments of methyl orange with persulfate were investigated, the experiment was prepared according to the literature [34]. As depicted in Fig.…”

“…The separation value Dm [ 200 cm -1 indicating a unidentate mode of coordination for the carboxylate group [30]. The bands at 3565-3547 cm -1 in the spectra of all the complexes 1, 2 and 3 were assigned to the t OH of water of crystallization [31] , whereas the t OH stretching vibrations of the coordinated water molecules were located in the range of 3218-3235 cm -1 for these complexes [32]. The IR Spectra of the compounds show a band at 1416-1464 cm -1 corresponding to t(C=N) stretching frequency of bpy [33].…”

Transition-metal coordination polymers [M(ndc) (bpy)Á(H 2 O)m]ÁxH 2 O (where M = Co(II), Ni(II), Cu(II)and Zn(II), ndc = 1,4-naphthalenedicarboxylate, bpy = 4,4 0 -bipyridine; m = 0 or 1; x = 1 or 2) were prepared by reacting the ligands and metal ions at room temperature with the aid of microwave irradiation and sonication methods. The structure of the coordination polymers was assigned based on elemental analysis, FT-IR and electronic spectral studies, thermal analysis, scanning electron microscope and X-ray powder diffraction. Thermogravimetric analysis was also used to follow up the possible thermal decomposition steps and to calculate the thermodynamic parameters of the nano-sized metal complexes. The kinetic parameters were calculated making use of the Coats-Redfern and Horowitz-Metzger equations. All obtained results of the different technics used in our study stated the ability to synthesis the metal coordination polymers of our interest using both microwave irradiation and sonication methods.
